BUTTON SEWING MACHINE Samuel W. Avis, Providence, It. I., assignor to The Reece Button Hole Machine Company; Boston, Mass., a corporation of Maine Application December 24, 1936, Serial No. 117,550

In Great Britain February 24, 1936 22 Claims.

This invention relates to machines for sewing on buttons, especially substantially flat buttons having perforations or holes through which the attaching thread is passed. Such buttons are of a wide variety of shapes and sizes, the number and spacing of the thread receiving holes differing in different buttons, and the number of stitches required for their satisfactory attachment varying I with the number of holes, the size of the buttons, and the purpose and location of their attachment.

In a prior application, Serial No. 89,330, filed July 7, 1936, by Franklin A. Reece and the present applicant jointly, is described and claimed an improved button sewing machine which can be set to attach either a two-hole or a four-hole button, having holes of any spacing within the range of the machine, by means of a variable number of groups of stitches of a variable number of stitches each, the thread being secured by a tying stitch at the completion of each group of attaching stitches. Said machine is entirely automatic and, having been set in operation with the work properly positioned therein, will perform and complete the sequence of operations-for which it has previoustly been set or adjusted and thereafter come to res The present application relates to certain portions or features of the operating and controlling mechanism of automatic button sewing machines of the ,type above referred to, which features were the sole invention of the present applicant.

The objects of the invention, together with means whereby the latter may be carried into eifect,.wi1l best be understood from the following description of an illustrative embodiment thereof shown in the accompanying drawings. The particular mechanism described and shown has, however, been chosen for purposes of exempliflcation merely, as it will be obvious to those skilled in the art that the invention, as defined by the claims hereunto appended, may be otherwise embodied without departure from the spirit and scope there- In said drawings:"
